QoS Configuration

Configuring Port Priority
Although the burst function helps reduce the packet loss ratio and improve packet
processing capability in the networks mentioned above, it may affect QoS
performance. So, use this function with caution.

Displaying QoS
By default, for a packet with an 802.1q tag header, a switch replaces the 802.1p
precedence of a packet with the priority of the receiving port and looks up the
new 802.1p precedence in the 802.1p-precedence-to-local-precedence mapping
table for the corresponding local precedence, and then assigns the local
precedence to the packet for it to be added an output queue.
Configuration prerequisites
The port whose port priority is to be configured is determined.
■
The target priority value is determined.
